Here are two references for you to look.  The reason “why?” is that applicants for Amateur-Built Experimental certificates do make mistakes that can be picked out at Airworthiness Inspections. Sometimes big ones.  The Airworthiness Inspector, for that day, (ASI or DAR) is there to verify conformity to the paperwork that applicant presents for that aircraft only. 

Your writing uses incorrect and out of date nomenclature of certificate holders and suggests that no one else is more creditable than you or the builder of that aircraft.  I have experienced applicants that had not even read the applicable parts of FAR 91, let alone FAR 45 or the Advisory Circular 90-89A pertinent to the Program Letter presented in the Application Packet..  They did not understand their responsibilities to present their aircraft, let alone operate it in preparation for first flight.  Big violations of the first paragraph of their Operating Limitations.  Big Risks to Public Safety.

On inspection day all applicants learn something very important for their operating safety if an ASI or DAR is doing a valuable job.

You may not like what I have presented here, but I did try to keep it brief enough and focused on your opening quotation.
